Summary

Canon's EF-S 10-22mm USM is one of the best quality ultra-wide-angle lenses in its range. As an EF-S model, it will only work on cropped-bodies, but the equivalent range of 16-35mm is ideal for capturing expansive landscapes, cramped interiors, large buildings or big group shots. The USM focusing is also quick and quiet, and again the optical quality is excellent. If you own a cropped-body and want a quality ultra-wide zoom, this is the one for you.

Canon EF-S 10-22mm geometry comparison

Canon 10-22mm wide angle geometry test
10-22mm EF-S at 10mm f8 (16mm equiv)
Distortion: 3.59% barrel
To measure and compare the Canon 10-22mm’s geometric distortion we photographed a test chart consisting of a grid pattern, using it and a number of rival lenses.The lenses were tested at their widest focal lengths with an aperture of f8 using a Canon EOS-400D in Aperture Priority mode.The images were analysed with Imatest using 5th Order line calculation and the full areas presented here at a reduced resolution.

The image above was taken with the Canon EF-S 10-22mm at 10mm f8. Barrel distortion was measured at 3.59% which is remarkably low considering the extreme wide angle coverage at this focal length. It’s roughly comparable to the distortion you’ll experience with the EF-S 18-55mm when it’s zoomed-out, and a significant improvement over the EF-S 17-85mm at 17mm. It’s also worth comparing against the EF 17-40mm tested on a full frame body, which delivers coverage almost as wide (17mm actual versus 16mm equivalent). In our EF 17-40mm review, geometric distortion at 17mm on an EOS 5D was measured at 6.39% – considerably higher. An impressive result here for the EF-S 10-22mm.

Distortion: 0.24% barrel

The lenses were tested at their longest focal lengths with an aperture of f8 using a Canon EOS-400D in Aperture Priority mode.To measure and compare the Canon 10-22mm’s geometric distortion we photographed a test chart consisting of a grid pattern, using it and a number of rival lenses.

The images were analysed with Imatest using 5th Order line calculation and the full areas presented here at a reduced resolution.

The image above was taken with the Canon EF-S 10-22mm at 22mm f8. While most lenses exhibit pincushion distortion when zoomed-in, the EF-S 10-22mm showed barrelling. This however isn’t that surprising considering the lens is still quite wide even when zoomed-in, and more importantly the actual degree of distortion at just 0.24% is very low. Judging from this and the above result, the EF-S 10-22mm is a good performer when it comes to geometric distortion, which will come as a relief to anyone shooting buildings indoors or out.
